LOCATIONS AND CLEARANCES
GENERAL
The eco2 air conditioning units are designed for outdoor
installation. When selecting a site for installation, be
guided by the following conditions:
• Unit must be installed on a level surface.
• For the outdoor location of the unit, select a place
having a minimum sun exposure and an adequate
supply of fresh air for the condenser.

JOHNSON CONTROLS
17
Installation
FORM 100.50-NOM6 (1207)
• Also avoid locations beneath windows or between structures.
• Optional condenser coil protection should be used
for seashore locations or other harsh environments.
• The unit should be installed on a roof that is structurally strong enough to support the weight of the unit
with a minimum of defl ection. It is recommended
that the unit(s) be installed not more than 15 feet
from a main support beam to provide proper
structural support and to minimize the transmission of sound and vibration. Ideally, the center of
gravity should be located over a structural support
or building column.
• Location of unit(s) should also be away from
building fl ue stacks or exhaust ventilators to
prevent possible reintroduction of contaminated
air through the outside air intakes.
• Be sure the supporting structures will not obstruct
the duct, gas or wiring connections.
away from sound sensitive areas such as conference
rooms, auditoriums and executive offi ces and any other
room that may have potential for tenant occupancy.
Possible locations could be above hallways, mechanical
or utility rooms.
Finally, service clearances should be maintained in
rooftop design to insure safe access to the unit. Unit
clearances are designed so that technicians have enough
space between units, building walls, and edges of
building to gain access safely. In cases where space is
limited, please call your local York representative for
additional information.
The clearances shown are to provide
adequate condenser airfl ow and service access to inside the unit. Additional clearance should be considered
for component replacement such as
compressors, evaporator coils, and
supply or exhaust fans.
LOCATION
Of the many factors that can effect the location of
equipment, some of the most important to consider are
Structural, Acoustical and Service clearances. Proper
attention should be made at the design stage to ensure
proper structural support. In cases where equipment is
being replaced, be aware of building design to insure
support is adequate for the application.
The next most important consideration in applying roof
top equipment is that of sound from the equipment.
Special care should be made to keep the roof top unit
While it is a common practice to operate the fan as soon as possible (air
movement during construction) on the
job site, the incomplete ductwork and
missing diffuser grilles will greatly
reduce air resistance and will allow
the fan to operate beyond design parameters. This practice may result in
water carry over and fl ooding of the
unit. Also, the supply fan motor may
overamp and become damaged.

RIGGING AND HANDLING
Proper rig ging and handling of the equip ment is
man da to ry during un load ing and setting it into position
to re tain warranty status. All lifting lugs must be used
to pre vent twisting and damage to the unit.
Care must be taken to keep the unit in the upright
po si tion during rigging and to prevent damage to the
water-tight seams in the unit casing. Avoid unnecessary
jar ring or rough handling.
Typical rigging using proper spreader bars and cables
is shown in Figure 2-3. See Figure 2-2 for number and location of the lifting lugs by unit size. It is also
mandatory that an ex pe ri enced and reliable rigger be
selected to han dle un load ing and fi nal place ment of
the equipment. The rig ger must be advised that the unit
contains internal com po nents and that it be han dled in
an upright po si tion. Care must be exercised to avoid
twisting the equip ment struc ture.

and regulations.
• Ground Level Locations – It is important that
the units be installed on a substantial base that
will not settle, causing strain on the refrigerant
lines and sheet metal and resulting in possible
leaks. A one piece concrete slab with footers
extended below the frost line is highly recommended. Additionally, the slab should be isolated
from the main building foundation to prevent
noise and vibration transmission to the building
structure.
For ground level installations, precautions should
be taken to protect the unit from tampering by, or
injury to, unauthorized persons. Erecting a fence
around the unit is common practice.

ROOF CURB INSTALLATION
YORK offers an optional roof curb designed specifi cally
for the eco2 foot print. This curb comes as an open
condenser model and is shipped disassembled and
requires fi eld assembly during installation. Refer to
the Installation Manual that is shipped with the roof
curb for specifi c instructions. For bottom supply and
return openings, the curb has matching connections to
ease installation.
The curb should be located according to the location
recommendations above, and properly sealed to prevent
moisture and air leakage into and out of the duct system.
Flexible collars should be used when connecting the
duct work to prevent unit noise transmission and
vibration into the building. The roof curb drawings
contained in the Johnson Controls literature are not
intended as construction documents for fi eld fabrication
of a roof curb. Johnson Controls will not be responsible
for the unit fi t up, leak integrity, or sound level with
fi eld fabricated roof curbs.
FORM 100.50-NOM6 (1207)
Construction documents for fi eld fabricated roof curbs
are available upon request.
Wood or fiber cant strips, roofing
felts, roofi ng material, caulking and
curb-to-roof fasteners are to be fi eld
supplied.

ELECTRICAL SERVICE SIZING
FORM 100.50-NOM6 (1207)
ELECTRICAL DATA
In order to use the electrical service required for
the cooling only eco2 rooftop, use the appropriate
calculations listed below from U.L. 1995. Based on the
confi guration of the rooftop, the calculations will yield
different MCA (minimum circuit ampacity), and MOP
(maximum overcurrent protection).
Using the following load defi nitions and calculations,
determine the correct electrical sizing for your unit. All
concurrent load conditions must be considered in the
calculations, and you must use the highest value for any
combination of loads.
Load Defi nitions:
• LOAD1 is the current of the largest motor – compressor or fan motor.
• LOAD2 is the sum of the remaining motor currents that may run concurrently with LOAD1.

• LOAD3 is the current of the electric heaters
– zero for cooling only units.
• LOAD4 is the sum of any remaining currents
greater than or equal to 1.0 amp.
Use the following calculations to determine MCA
and MOP for units supplied with a single-point power
connection:
MCA = (1.25 x LOAD1) + LOAD2 + LOAD3 + LOAD4
MOP = (2.25 x LOAD1) + LOAD2 + LOAD3 + LOAD4
If the MOP does not equal a standard current rating
of an overcurrent protective device, then the marked
maximum rating is to be the next lower standard rating.
However, if the device selected for MOP is less than the
MCA, then select the lowest standard maximum fuse
size greater than or equal to the MCA.
